They will not, however, turn a guest into a (hardware accelerated) host. they might let a VM directly access a GPU. VM acceleration features allow you to use your hardware more effectively inside a VM, e.g. (I guess it is possible to emulate an entire VM using software, without hardware-acceleration, but this makes the VM incredibly slow so I wouldn't recommend this. If Linux is your host, Hyper-V is not the host. Kind of by definition, VMs are hosted from a host.

As far as I know, you cannot host hardware-accelerated VMs from a VM. Hyper-V features are for hosting virtual machines (VMs). Should set the guest OS type to 'Hyper-V.' Under Workstation 9, Player 5 or Fusion 5, you Hyper-V performs relatively poorly as a guest hypervisor under ESXiĥ.0, but it performs reasonably well under Workstation 8, Player 4 or Fusion 4 (or later). Run under ESXi 5.0, Workstation 8, Player 4 or Fusion 4 (or later). Hyper-V requires hardware-assisted virtualization, so it can only be VMWare also has extensive support for multiple nesting scenarios in its commercial products: The hypervisor that runs on the real hardware isĬalled a level 0 or L0 the hypervisor that runs as a guest on L0 isĬalled level 1 or L1 a guest that runs on the L1 hypervisor is called Nested virtualization is the ability to run a hypervisor inside of a The open source Xen hypervisor also claims support for nested virtualization: The technology is still very new and appears to still be in preview. In other words, nesting allows you to run the Hyper-V Nested virtualization is running virtualization inside a virtualizedĮnvironment. It's still being actively commented on and requested as recently as, but as of May 2015 the developers still have 'different priorities.'Īs of the Windows 10 Fall Update (and the Windows Server 2016 previews), Hyper-V is now capable of nesting a Hyper-V hypervisor: Unfortunately, that request has been around for 6 years now, and the devs initially indicated that it would only be of 'limited usefulness.' With more and more SW relying on virtualization (Windows Mobile Emulation, Android Emulation, Vagrant, etc.), I would hope that it becomes a higher priority.

You can vote up the feature request for VirtualBox here. This technology is referred to as nested virtualization. Yes, it is now possible to use Hyper-V on a Windows guest OS, but not with VirtualBox.
